I have a set of Billet UPR speaker grilles for the 05+ Mustangs. They screw onto the plastics covers. Has anyone here installed them? i tried tonight and they do not fit properly. The actual woofer comes past the factor plastic cover by just a bit, and the UPR bezel sits flush, and does not give the wooef enough room, so the cover never clicks down properly.

I am wondering if putting some sort of spacer between the bezel and the plastic cover would help, but just wonderinf what others have done.

Thanks,

Sean
